The invention of the balloon-expandable stent
An estimated 2 million stents are implanted into people’s hearts around the world each year – making it one of the key treatments for heart disease.
The treatment was invented by Argentinian doctor Julio Palmaz, who credits a piece of metal being left by a construction worker in his home as inspiration for the structure of the stent.
Collaborating with a US Army cardiologist and getting funding from the owner of a fast-food chain and a pharmaceutical giant; the coronary stent was approved for use in human beings in the 1990s.
Julio Palmaz speaks to Tim O’Callaghan about his invention.
Eye-witness accounts brought to life by archive. Witness History is for those fascinated by the past. We take you to the events that have shaped our world through the eyes of the people who were there.
For nine minutes every day, we take you back in time and all over the world, to examine wars, coups, scientific discoveries, cultural moments and much more.
